Among the 123 ZCONF=2 or 3 sources, 18 galaxies are located at \(z=2.86\) –\(3.77\)  and \(z=3.91\) –\(4.44\) , while 105 galaxies are outside the redshift range. Unfortunately, one galaxy, which is categorized as an LAE in the catalog of [1]} and shows UV lines in the MXDF data cube, has \(\mbox{Ly$\alpha $}\)  emission in the AO gap. Due to the limited spatial resolution of MUSE, RID=7876 and 9944 were assigned to a unique MUSE source (MID=103 at \(z_{\rm s}\) =2.99). Such nonisolated sources were separately treated as described later.
